儿童原发性腹膜后恶性肿瘤的诊断与治疗

分析原发性腹膜后恶性肿瘤１２例。８３％以腹块和腹痛为主要症状，体征中腹块占９１．５％，以恶性淋巴瘤居首位占６１％。全组完全切除率为５８％，行脏器联合切除占２５％。完全切除加放疗、化疗３年存活率为２８．５％，部分切除及活检未给其它治疗者５例预后差，均１年内死亡，差别显著。     

种植受体血管内皮细胞在异种血管移植中的实验研究

目的　探讨种植受体血管内皮细胞在抗异种血管移植超急排斥反应 (HAR)方面的意义。方法　选用豚鼠→大鼠移植模型 ,先将分离、培养的大鼠动脉内皮细胞种植于去内皮的豚鼠动脉内壁 ,再将此豚鼠动脉植入大鼠体内 ,观察动脉血栓形成时间 ,并采用免疫组化技术检测了 Ig M、C3在移植后豚鼠动脉壁上沉积的情况。结果　已种植大鼠内皮细胞的豚鼠动脉血栓形成时间 (2 0 .3± 4.42 h)较植入大鼠体内的正常豚鼠动脉 (0 .35± 0 .2 84h)以及单纯去内皮豚鼠动脉血栓形成时间 (0 .16 5± 0 .0 77h)显著延长 (P<0 .0 0 1)。免疫组化结果显示 ,植入大鼠体内的正常豚鼠内皮细胞表面有 Ig M和 C3沉积 ,而预先种植大鼠内皮细胞的豚鼠动脉内壁无 Ig M和 C3沉积。结论　在异种供体血管壁上预先种植受者血管内皮细胞 ,可延长移植的异种供体血管通畅时间 ,该技术可能在抗异种血管移植 HAR方面具有重要意义     

TAXUS支架治疗急性冠状动脉综合症的疗效评价

目的评价紫杉醇洗脱冠状动脉支架(TAXUStmBoston公司产品)应用于急性冠状动脉综合症病人的临床疗效及安全性。方法自2003年5月至2004年12月接受TAXUS支架治疗的94例急性冠状动脉综合症患者,观察术后即刻效果、术后6个月心脏性死亡、心肌梗塞、再次血管重建及冠状动脉造影复查情况。病例中包括ST段抬高的急性心肌梗塞27例,非ST段抬高的急性心肌梗死8例,不稳定心绞痛59例。结果支架植入成功率为99%,术中和随访期间无死亡,术后1例出现亚急性血栓,1例晚期血栓致心肌梗塞,另有5例随访中进行了血管重建术,6个月主要心脏不良事件(MACE)发生率7.4%。术后6～7个月23例的冠状动脉造影复查再狭窄率为13.0%(支架内为8.6%),靶病变重建率为2.7%。结论应用TAXUS支架治疗急性冠状动脉综合症是安全和有效的,支架内再狭窄率明显低于普通金属支架。

Elimination of malignant clonogenic cells from human bone marrow using multiple myeloid cell-specific monoclonal antibodies and complement.

Single or combined monoclonal antibodies (McAbs) Zh53, Zh820, and Zh2-1 have been used to eliminate malignant clonogenic cells from human bone marrow. The test of cytotoxicity showed that all of these McAbs could express high specific cytotoxic action against HL-60 cells and were selectively complement-dependent cytotoxic to various types of fresh leukemic cells. Clonogenic assay detected that single treatment with antibody and rabbit complement (RC) could reduce clonogenic units of HL-60 cells by more than 2 logs and two treatments reduced clonogenic units by more than 4 logs. However, combination of 2 McAbs could reduce clonogenic units by 4-5 logs. The data suggest that multiple treatments with McAbs and RC or a combination of 2 McAbs are more effective than a single treatment in eliminating clonogenic tumor cells. Treatment of normal human bone marrow with Zh53, Zh2-1 and RC did not produce a loss of normal CFU-GM, but treatment with Zh820 reduced the clonic units of normal CFU-GM by 24%.

     

Studies on Toxicity of Nitroquine-Dapsone Compound and Therapeutic Effects of Folic or Folinic Acid on Toxicated Animals

The toxic effects of nitroquine-dapsone compound(NQD)in mice and dogs were studied.The therapeutic index of NQDin mice is 1911,the greatest among the 6 antimalarials tested.Thetoxic effects of NQD(50 mg/kg/day for 3 days per os)and nitro-quine in dogs were manifested by injuries on the adrenal cortexand intestinal epithelium.When folic acid(4 mg/kg/day for 4 days)or calcium leucovorinum(0.3 mg/kg/day for 4 days)were usedconcomitantly with NQD,the death rate and the incidence of dia-rrhea in the toxicated dogs were greatly reduced,the injury on theintestinal epithelium was much milder,and the goblet cells weremuch more numerous than those without treatment.The results suggestthat folic acid and calcium leucovorinum can protect the undifferen-tiated cells in the intestinal crypts from being injured by NQD.
